high bp and 4 weeks pregnant today

Okay my blood pressure is usually 98/59.
Once I got pregnant it seemed to shoot up to 139/88. I checked it last night just to keep an eye on it and its now 141/72. Granted I will confess I did have some caffeine prior to taking my blood pressure.. going to test again today to see.. but have any of you had a blood pressure like this? What was your treatment or does this just sorta happen once in awhile?
